British singer Ed Sheeran has pulled out of a North American tour with Snow Patrol in order to return to England due to "personal reasons".The A Team hitmaker has been opening for the group on their current tour of the U.S. and Canada, but he has now cancelled his appearance at the remaining performances to attend to a personal matter. In a series of posts on his Twitter.com page, he writes, "Sorry to announce that I have to miss the last 4 days of the Snow Patrol tour, have to get back to England, but I'll be back in June and Sept (sic). Hope everyone understands, lots of love... "So sorry to cancel, have to get home for personal reasons." However, Sheeran assured fans he will be back on the road soon, adding, "I'm announcing a full US and Canada headline tour beginning of June, for anyone that's missed out on shows this time round."
